Display data in a scatter plot

Recently I tried to use the CPA for a dotplot. As soon as I try to display the data in logarithmic scale there is an error. What can I do?
Thanks in advance, Dominik

Hi Dominik,

Can you tell me what measurements you are plotting? Also, are any values of these measurements negative? (logarithms are undefined for negative values).

Hi Mark,

actually I am trying to display CD45 and CD14 integral intensity values. There should be no negative values. Moreover, displaying this kind of data is no problem e.g. in sigma plot, even not in logarithmic scale.


In that case, could you reprint the error message in full?
